SHUTTER OR DOOR.

SPECIFICATION forming part of Letters Patent No. 585,239, dated June 29,1897.

Application filed April 5, 1897. Serial No. 630,779. (No model.)

To @ZZ w/'Lont t may concer/t:

Beit known that I, WILLIAM J. SPRANGERS, a citizen of the United States,and a resident of l-Iolland, in the county of Brown and State ofWisconsin, have invented certain new and useful Improvements in Shuttersor Doors; and I do hereby declare that the following' is a full, clear,and exact description thereof.

My invention has for its object to provide an outside shutter or doorthat may be utilized in summer as an insect-screen and in winter as aweather-shield. Therefore it consists in certain peculiaritos ofconstruction and combination of parts hereinafterset forth withreference to the accompanying drawings and subsequently claimed.

Figure l of the drawings represents a side elevation of a shutterconstructed according` to my invention and partly broken away; Fig. 2, avertical section viewed on the plane indicated by line 2 2 in Fig. l,and Fig. 3 a horizontal section indicated by line 3 3 in Fig. l.

Referring by letter to the drawings, Arepresents a perforated plate ofsheet metal having portions thereof bent upon a preferably metal frame Band riveted thereto, the edges of the plate being turned inward to abutthe frame, as herein shown.

Opposing the plate A between the latter and its rccurved edges isanother perforated sheet-metal plate O, the latter having adjustment tobring its perforations in or out of register with those in the formerplate, as hereinafter more fully described.

To provide for adjustment of plate O, the latter is of less dimension inone direction thereof than the inside of the frame B, as clearlyillustrated in Fig. 2, and the plate A is provided with slots b in thedirection of the adjustment, these slots serving as guides for screws cd, connecting said plate O and a bar D, the latter having play on theoutside of the stationary plate. Washers are interposed between theplate O and heads of the screws c d, and the head of the latter screw isshown provided with wings e, by which said screw may be readily operatedto clamp said plate O in adjusted position against the one on which itslides.

Vhen the perforations of plate O are brought into register with those`of plate A, the shutter or door serves to admit outside air and at thesame time exclude insects, but if a reverse adjustment of said plate behad the structure of which it forms a part will exclude weather when inclosed position in a casing to which it may be hinged.

The blind or door above specified being preferably metal throughout itis reproof and very durable.

Having thus described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is-

l. A shutter or door comprising aframe, a perforated plate of sheetmetal made fast to the frame and having recurved edges abutting thesame, another perforated but rnovable sheet-metal plate opposing the oneaforesaid between the latter and its reeurved edges, and suitable meansfor effecting adjustment of the movable plate to bring its perforationsin or out of register with those in the stationary plate.

2. A shut-ter or door comprising a frame, a slotted and perforated plateof sheet metal made fast to the frame and having recurved edges abuttingthe same, another perforated but movable sheet-metal plate opposing theone aforesaid between the latter and its recurved edges, a slide-baroutside the stationary plate, and screws that have play in the slots ofthe Ilatter plate but connect the movable plate and slide-bar.

In testimony that I claim the foregoing I have hereunto set my hand, atHolland, in the county of Brown and State of Wisconsin, in the presenceof two witnesses.

WILLIAM J. SPRANGERS.
